Poisonous snakes are found in all parts of the world except Antarctica. They are usually easy to identify because they have two distinct features: fangs and venom. Fangs are long sharp teeth that snakes use to inject venom into their prey. Venom is a poisonous substance that snakes produce in their bodies.
There are two types of poisonous snakes: those that are venomous and those that are not. Venomous snakes have a pair of glands that produce venom which they use to kill their prey. These snakes are found in all continents except Antarctica. Non-venomous snakes on the other hand do not have these glands. They kill their prey by squeezing them to death.
There are three ways to identify a poisonous snake: by its appearance by its behaviour and by the symptoms it produces in humans.
1. Appearance
Poisonous snakes usually have bright colours that serve as a warning to predators. They may be patterned or have markings that make them look dangerous. Some species of snakes such as the king cobra have hoods that they can spread when they are threatened.
2. Behaviour
Venomous snakes are often aggressive and they may strike without warning. They may also coil and shake their tails when they feel threatened. Non-venomous snakes on the other hand are usually shy and will attempt to flee when they feel threatened.
3. Symptoms in humans
If a person is bitten by a poisonous snake they may experience symptoms such as swelling pain and difficulty breathing. In some cases the bite may even be fatal.
